The instrumented test system and the analysis for a novel tactile sensor are proposed to examine the material characteristic parameters on the basis of the indentation contact mechanics. A conjugate twin-strain-gage attached to the inner surface of a spherical glass-bowl-indenter senses in a differential manner the contact stress distribution beneath the indenter, and then allows to characterize the viscoelastic properties of the material indented. The indentation contact tests are conducted for polymer (polylactic acid, PLA) and candy (furan polymer) . The test results suggest the potential applications of this tactile sensor to the mechanical characterizations of viscoelastic materials as well as pure elastic and elastoplastic materials.
